TECHNICAL FIELD The present invention relates to a bathroom chair with a shower device, and more particularly, a bathroom chair with a shower device, in which a water supply pipe is arranged in the arms of the shower device, and water remaining inside can be discharged from the tip of the pipe through a drain hole. Regarding chairs.

Traditionally, it has been difficult for elderly people, people requiring nursing care, and physically handicapped people to take a shower or wash their bodies while standing. A bathroom chair with a shower unit has been developed so that the user can take a shower.

For example, Japanese Patent Application Laid-Open No. 2019-587 (Patent Document 1) describes a chair body consisting of a seat on which the user sits, a backrest that supports the back, and legs that support these parts, Above the backrest, a passage structure whose one end is supported by the chair body and an injection nozzle are attached. A chair with a shower function is disclosed, which includes a shower device comprising:

In the chair with a shower function described in Patent Document 1, since a pair of left and right shower arms supported by the chair body extend forward and downward from above the backrest, the injection nozzles attached to the shower arms spray the seated person. Hot water or cold water can be efficiently jetted over a wide range toward the upper half of the body.

However, in the shower device described in Patent Document 1, since the shower arm is arranged on the upper part of the chair body, there is a problem that the high center of gravity of the chair makes the chair overturn easily and causes instability. This problem was accentuated when water was present in the shower apparatus.

In addition, in the shower device described in Patent Document 1, a small-diameter pipe is used for the shower arm to reduce the weight and suppress the heightening of the center of gravity of the chair. When water is present in the shower device when the chair is to stand on its own, there is a problem that the weight of the water remaining in the shower arm prevents the chair from stably standing on its own. In other words, in order to reduce the influence of the weight of the water remaining in the shower arm when the chair is folded and made to stand on its own, the shower arm should be pulled out of the chair when the front and rear legs of the chair are closed. There is a constraint that the shape of the shower arm must be approximately linear so that it can be placed between the front and rear legs of the seat (Fig. 4 of Patent Document 1). There was a problem that it was not possible to arrange them appropriately.

Furthermore, in the shower device described in Patent Document 1, the shower arm is rotated with respect to the upper end horizontal pipe (passage structure) in accordance with the seating position of the seated person, and a hard pipe is used to maintain that state. There must be. For this reason, in the shower device described in Patent Document 1, a universal joint must be used to rotatably connect the shower arm to the upper end horizontal pipe (passage structure). There was a problem that water leakage from the universal joint was unavoidable due to wear of parts.

Japanese Patent Application Laid-Open No. 2019-587

Therefore, the present invention enables the bathroom chair to stand stably on its own without being affected by the water remaining inside the shower device even when the chair is folded, and allows the shower arm to be arranged with a high degree of freedom. To provide a bathroom chair with a shower device in which leakage of water from joints (connections) of a shower arm is prevented.

The inventors of the present invention have made intensive studies on the structure of the variable part of a bathroom chair with a shower device for appropriately arranging the position of the shower nozzle according to the physique of the user. We found that the above problem can be solved by arranging a water supply pipe such as a flexible hose to form a double pipe structure, and by providing a drain hole at the tip of the water supply pipe for discharging water to the outside by its own weight. The present invention has been completed.

That is, according to the present invention, a bathroom chair to which a shower device to be described later is attached comprises a front leg, a rear leg rotatably supported by the front leg, and a rotatable front leg or rear leg. The chair body is composed of a seat pivotally supported by the chair, a backrest support extending upward from the front legs, and a backrest attached to the backrest support. Further, a shower device attached to a chair for a bathroom includes a device body having a connection portion to which water is supplied from the outside, and a device body rotatably attached to the device body. and a shower arm (hereinafter also referred to as “arm portion”) provided with a plurality of discharge holes for discharging to the outside.

According to the present invention, a flexible water supply pipe extending from the connecting portion is arranged in the apparatus main body and the arm portion, and the discharge hole directly connects to the water supply pipe. and a water drain hole is provided at the tip of the water supply pipe for discharging residual water accumulated in the water supply pipe to the outside of the arm. is provided.

In the shower device of the present invention, arm 7 includes a first arm, a joint and a second arm. The first arm constituting the arm is rotatably attached to the device main body, and the joint is rotatably attached to the first arm. , and the second arm is rotatably attached to the joint. Therefore, in the present invention, water does not directly pass through the device main body and the arms, but passes through the device main body, the first arm, the joint and the second arm. By arranging a water supply pipe from the connecting part to the drain hole to form a double-pipe structure, water leakage from the movable part (connecting part) of each element of the device main body and the arm is prevented.

Further, in the shower apparatus of the present invention, in order to improve the sealing performance of the entire arm, each discharge hole is attached so as to directly communicate with the water supply pipe, and each discharge hole is connected to the first arm and the second arm. It is mounted so that it can only be supported by two arms.

Therefore, the water supplied from the outside through the connecting portion of the device main body reaches the discharge hole without leaking to the outside of the water supply pipe unless the water supply pipe is damaged, and is discharged to the outside from the discharge hole. Therefore, the shower device of the present invention has high sealing performance. In addition, since the water supply pipe arranged in the arm is flexible, even if the first arm, the joint and the second arm rotate arbitrarily, the water supply pipe is Bending, twisting, etc., which occur in the body can be easily absorbed by its flexibility and elasticity, and the high sealing performance of the shower device of the present invention can be maintained.

Since the bathroom chair with a shower device of the present invention is equipped with a shower device on its upper part, in order to avoid facilitating the overturning and destabilization of the chair due to the high center of gravity of the bathroom chair, as described above, The weight of the shower device is reduced by using lightweight materials and members. However, since water is supplied to the main body and arms of the shower device from the outside, if there is water in the shower device, the high center of gravity of the bathroom chair will make the chair unstable. Stabilization is a problem, especially when the front and rear legs of the bathroom chair are closed and folded to stand on its own.

Therefore, in the present invention, as described above, by arranging the water supply pipe in the device main body and the arm portion to form a double-pipe structure, even if water exists in the shower device, the device main body and By reducing the amount of water that stays in the water supply pipe rather than in the inner space of the arm, it is possible to prevent the bathroom chair from falling easily and becoming unstable due to the high center of gravity of the bathroom chair.

Furthermore, in the shower device of the present invention, since the water drain hole is provided at the tip of the water supply pipe, when the arm is turned downward to be in the retracted state, the arm is more likely to move than the water drain hole. Residual water accumulated in the water supply pipe is discharged to the outside of the water supply pipe and the arm through the drain hole by external air flowing in from another discharge hole arranged on the root side (upper side) of the part. and the weight of the entire shower apparatus is reduced. In addition, even if the shower hose or the like connected to the connection part of the device body is removed, external air will flow in from the connection part, so the residual water accumulated in the water supply pipe will drain through the water supply pipe and the arm part through the drain hole. is discharged to the outside of the shower apparatus, and the weight of the entire shower apparatus is reduced.

As a result, even when water is present in the shower device, the bathroom chair equipped with the shower device of the present invention can easily fall over and prevent destabilization due to the high center of gravity of the bathroom chair. In addition, even when the front legs and rear legs of the bathroom chair are closed and folded, the bathroom chair can be stably made independent.

In addition, although the present invention discloses a configuration in which water is not directly passed through the device main body and the arms, and a water supply pipe is arranged in the device main body and the arms to form a double pipe structure, the device If it is possible to ensure the sealing performance of the moving parts of the main body and arm parts, water can be passed directly through the device main body and the arm parts and communicated with the discharge holes directly attached to the arm parts. A configuration in which water is discharged to the outside of the device main body or the arm may be employed. Further, in this case, by providing a drain hole communicating with the inside at the tip of the second arm, it is possible to obtain the same effect as in the case where the device main body and the inside of the arm have a double-tube structure. can.

In addition, when the device main body and arms have a double-pipe structure, even when not having a double-pipe structure, the drain hole can also be used as a discharge hole when using the shower device. You may make it function as a discharge hole. In this case, since only one nozzle is required for the drainage hole and the discharge hole, the shower device can be constructed with an extremely simple structure without requiring a special part such as an on-off valve.

According to the bathroom chair with a shower device of the present invention, water is not directly passed through the device main body and the arm portions, and the device main body, the first arm portion, the joint portion and the first Since the water supply pipe is arranged from the connection part to the drain hole through the arm part of 2 and has a double pipe structure, water leakage from the movable part (connection part) of each element of the device body and arm part is prevented. be done. Especially according to the present invention, since the water supply pipe arranged in the arm has flexibility, the first arm, the joint and the second arm can be freely rotated. Also, bending, twisting, etc. occurring in the water supply pipe can be easily absorbed by its flexibility and elasticity, so that a high degree of sealing performance of the shower apparatus can be maintained.

According to the present invention, by arranging the water supply pipe in the device main body and the arms to form a double-pipe structure, even when water exists in the shower device, the inside of the device main body and the arms can be Since the amount of water remaining in the water supply pipe can be reduced more than in the space, it is possible to prevent the chair from falling easily and becoming unstable due to the high center of gravity of the bathroom chair.

According to the present invention, since the water drain hole is provided at the tip of the water supply pipe, especially when the arm is rotated downward and put into the storage state, the base of the arm is more likely to be exposed than the drain hole. The remaining water accumulated in the water supply pipe is discharged to the outside of the water supply pipe and the arm through the drain hole by external air flowing in from other discharge holes arranged on the side (upper side) of the shower. The weight of the entire device is reduced. In addition, even if the shower hose or the like connected to the connection part of the device body is removed, external air will flow in from the connection part, so the residual water accumulated in the water supply pipe will drain through the water supply pipe and the arm part through the drain hole. is discharged to the outside of the shower apparatus, and the weight of the entire shower apparatus is reduced.

As a result, the bathroom chair equipped with the shower device of the present invention can easily fall over and prevent destabilization due to the high center of gravity of the bathroom chair even when there is water in the shower device. In addition, even when the front legs and rear legs of the bathroom chair are closed and folded, the bathroom chair can be stably made independent.

A cover support piece 907 of the cover plate 904 is provided with a pair of cylindrical portions 91 that form a space apart from the support piece 903 when the cover support piece 907 is brought into contact with the support piece 903 and screwed.

In the shower device 6 and the shower-equipped bathroom chair 1 of the present embodiment, the height adjusting means 9 of the shower device 6 is configured to insert and support the two struts 63 extending from the device main body 60 as described above. a cylindrical portion 91, a fixing member 92 supported by the cylindrical portion 91 and spaced close to the column 63, and a clamping member 93 disposed between the inner peripheral surface of the cylindrical portion 91 and the column 63. I have.

More specifically, in the height adjusting means 9 of this embodiment, the fixing member 92 has a female screw opening (not shown) in the side wall portion of the cylindrical portion 91 , is screwed into the female screw, and is directed toward the column 63 . It is composed of a male screw 92 with a knob that is screwed forward and backward. The holding member 93 is arranged between the inner peripheral surface of the cylindrical portion 91 and the support 63 and between the fixing member 92 (hereinafter also referred to as “male screw 92”) and the support 63. and a position facing the first holding member 930 and between the inner peripheral surface of the cylindrical portion 91 and the post 63. and a second holding member 931 that abuts on the other side surface of the post 63 .

As described above, in the shower device 6 of the present embodiment, two struts 63 extending from the device body 60 are provided to support above the chair body 10 the device body 60 to which the pair of left and right arms 7 are connected. have. For this reason, in this embodiment, a cylindrical portion 91 for inserting and supporting the column 63 is provided, and by screwing together the male screw 92 supported by the cylindrical portion 91 to be close to and away from the column 63, The height of the apparatus main body 60 supported by the support 63 can be adjusted by using the support 63 of the apparatus main body 60 . That is, by separating the male screw (fixing member) 92 from the post 63, the height of the device main body 10 supported by the post 63 is adjusted, and the male screw (fixing member) 92 is brought into contact with the post 63, or the position is adjusted as described later. The device body 60 supported by the pillars 63 can be fixed at a desired height by bringing them into contact with each other via the holding member 93 . Note that the cylindrical portion 91 for inserting and supporting the support column 63 may be a member that can be fixed to the chair body 10, such as the backrest portion 5, and may be integrally formed, such as being built into the chair body 10. .

The shower device 6 of the present embodiment uses a lightweight material such as resin for the device main body 60 and supports 63 and the like in order to prevent the bathroom chair 1 equipped with the shower device 6 from easily falling due to the high center of gravity. The weight of the entire shower device 6 is reduced by using a lightweight member such as a hollow metal pipe made of stainless steel, aluminum, or the like for the frame member.

For this reason, the height adjusting means 9 of the present embodiment is designed so that even if the male screw 92 is pressed against the support 63 which is light but relatively weak in strength, the support 63 is not deformed, or a moment force is applied to the support 63 . In order to prevent the struts 63 from being easily bent by the upper and lower edges (corners) of the tubular portion 91 when working, the inner peripheral surface of the tubular portion 91 and the struts 63 are provided inside the tubular portion 91. A first clamping member 930 abutting on one side surface of the column 63 between the male screw 92 and the column 63 and a cylindrical portion 91 located opposite the first clamping member 930 A second holding member 931 abutting on the other side surface of the support 63 is arranged between the inner peripheral surface of the support 63 and the support 63 . In other words, the first clamping member 930 and the second clamping member 931 also function as protective members that prevent the post 91 from being damaged by the male screw 92 and the upper and lower edges of the tubular portion 91 .

In this way, the first holding member 930 and the second holding member 931 hold the support 63 from both sides, and the first holding member 930 is positioned between the inner peripheral surface of the cylindrical portion 91 and the support. 63 and between the male screw 92 and the post 63, the post 63 is pressed by bringing the male screw 92 closer. In addition, since the second holding member 931 is arranged at a position facing the first holding member 930 and between the inner peripheral surface of the cylindrical portion 91 and the post 63, the pressure exerted by the first holding member 930 is reduced. The post 63 is pressed by receiving the reaction force of the pressure.

In the height adjusting means 9 of this embodiment, the cross section of the column 63 has a circular shape by using a hollow metal pipe for the column 63, so that the first and second clamping members 930 and 931 have a circular shape. is provided with an inner contact surface 932 that makes contact with the outer peripheral surface of the post 63 by two or more line contacts. More specifically, the inner contact surface 932 has a It has a semi-hexagonal shape with sides (Fig. 5).

In the height adjusting means 9 of the present embodiment, the support 63 has a circular cross section, and the inner sides of the first and second holding members 930 and 931 are provided with two support members 930 and 931 with respect to the outer peripheral surface of the support 63 . By forming the inner abutment surface 932 that makes contact with the line contact as described above, the pressing force transmitted from the tip of the male screw 92 and the inner wall surface of the cylindrical portion 91 to the support 63 is appropriately distributed and concentrated, and damage to the support 63 is prevented. Both prevention (protection) and strengthening of clamping force against the strut 63 are achieved.

In addition, in the height adjusting means 9 of the present embodiment, the cross-sectional outline of the inner contact surfaces 932 of the first and second holding members 930 and 931 is formed to have a semi-hexagonal shape with three sides. Therefore, it is possible to prevent the holding force from changing the number of line contacts between the inner contact surface 932 and the outer peripheral surface of the post 63 and making the holding force unstable. In addition, when the support 63 is pressed by the first and second holding members 930 and 931, the inner contact surface 932 is prevented from being expanded by the support 63 and cracked due to stress concentration.

As shown in FIG. 5, a half-hexagon having a cross-sectional shape with three sides is a cylindrical body having six side surfaces and a hexagonal cross-section, as shown in FIG. It means the shape of either half of a cylindrical body when it is divided into two almost equally by a longitudinal section passing through a corner, and in this case, the half cylindrical body has an inner surface consisting of three faces. , and its cross section has a semi-hexagonal shape with three sides.

In addition, in the height adjusting means 9 of this embodiment, the vertical length of the inner contact surfaces 932 of the first and second holding members 930 and 931 is equal to the inner peripheral surface of the cylindrical portion 91 with which the holding members 930 and 931 come into contact. (Fig. 7). Therefore, in this embodiment, the support 63 pressed by the first and second holding members 930 and 931 can be prevented from coming into contact with the upper and lower edges (corners) of the cylindrical portion 91 surrounding the support 63. It is possible to effectively prevent the inconvenience that the support 63 is easily bent due to direct contact with the upper end edge and/or the lower end edge of the tubular portion 91 when a moment force acts on the support 63 . For this reason, the first and second holding members 930 and 931 have folded portions 933 that cover the upper edge and lower edge of the tubular portion 91 (FIG. 5).

Thus, the vertical length of the inner abutment surface 932 is longer than the vertical length of the inner peripheral surface of the tubular portion 91, and the first and second clamping members 930, 931 are positioned at the upper edge and lower end of the tubular portion 91, respectively. With the folded portion 933 covering the edge, for example, by forming a curved surface with an R on the inner surface of the folded portion 933, when a moment force acts on the column 63, the column 63 will move toward the first and second ends. Since the pillar 63 comes into contact with the rounded curved surfaces of the two clamping members 930 and 931, even if the support 63 comes into contact with the upper and lower edges of the first and second clamping members 930 and 931, it becomes more difficult to bend. Also, it is possible to prevent the first and second holding members 930 and 931 from slipping off from the cylindrical portion 91 due to vertical displacement.

The clamping member 93 must have a hardness capable of securely restraining the support 63 when it is clamped therebetween. It must be able to deform flexibly with the movement of the strut 63 without causing damage. For this reason, the first holding member 930 and/or the second holding member 931 are made of a resin material such as polypropylene having a Rockwell hardness of 70 to 110 on the R scale and an elastic modulus of 1100 to 1700 MPa. preferably.

Configuration of chair independence support mechanism FIG. 8 shows the internal structure of a part of the arm part 7 of the shower device 6 of this embodiment, and the bathroom chair 1 with the shower device that is self-supporting with its legs closed is viewed from the front. A perspective view is shown. 9 shows a side view of the shower-equipped bathroom chair 1 shown in FIG. 8, showing the internal structure of part of the arm portion 7 of the shower device 6 of this embodiment.

As shown in FIGS. 8 and 9, the shower device 6 to be attached to the bathroom chair body 10 of this embodiment includes a device body 60 having a connection portion 61 to which water is supplied from the outside as described above. and an arm portion 7 which is rotatably attached to the device main body 60 and provided with a plurality of nozzles (discharge holes) 8 for discharging water supplied to the inside from a connection portion 61 to the outside. there is A flexible water supply pipe 73 such as a resin hose extending from the connection portion 60 is arranged in the device main body 60 and the arm portion 7 , and the nozzle 8 is directly connected to the water supply pipe 73 . Further, at the tip of the water supply pipe 73, a drain hole 80 is provided for discharging residual water accumulated in the water supply pipe 73 to the outside of the water supply pipe 73 and the arm portion 7. .

In the shower device 6 of the present embodiment, the first arm portion 70 constituting the arm portion 7 is rotatably attached to the device main body 60, and the joint portion 72 is rotatably attached to the first arm portion. 70 and the second arm 71 is rotatably attached to the joint 72 . For this reason, in the present embodiment, water is not directly passed through the device main body 10 and the arm portion 7, and the device main body 10, the first arm portion 70, and the joint portion 72 are contained in the device main body 10 and the arm portion 7. And by arranging a water supply pipe 73 from the connecting portion 61 to the drain hole 80 through the second arm portion 71 to form a double pipe structure, each element 70, 72, 71 of the device main body 10 and the arm portion 7 It prevents water from leaking from the moving parts (connecting parts) of the

Further, in the shower device 6 of the present embodiment, each nozzle 8 is attached so as to directly communicate with the water supply pipe 73 in order to improve the sealing performance of the entire arm portion 7, and each nozzle 8 is connected to the first It is mounted so as to be supported only by arm 70 and second arm 71 .

Therefore, the water supplied from the outside through the connection portion 61 of the device main body 60 reaches the nozzle 8 without leaking to the outside of the water supply pipe 73 unless the water supply pipe 73 is damaged. Therefore, the shower device 6 of this embodiment has a high sealing property. Further, since the water supply pipe 73 arranged in the arm portion 7 has flexibility, the first arm portion 70, the joint portion 72 and the second arm portion 71 can be freely rotated. Also, bends, twists, and the like that occur in the water supply pipe 73 are easily absorbed by its flexibility and elasticity, and the shower device 6 of the embodiment can maintain a high degree of sealing performance.

Since the bathroom chair 1 with a shower device of the present embodiment is equipped with a shower device 6 on its upper part, the chair 1 is easily overturned due to the high center of gravity of the bathroom chair 1, and the destabilization is avoided. As described above, the weight of the shower device 6 is reduced by using lightweight materials and members. However, since water is supplied from the outside to the main body 60 and the arm portion 7 of the shower device 6, if water exists in the shower device 6, the chair 1 will have a high center of gravity. In particular, when the front legs 20 and the rear legs 3 of the bathroom chair 1 are closed and folded to stand on its own, this problem becomes significant.

Therefore, in this embodiment, as described above, the water supply pipe 73 is arranged in the device main body 60 and the arm portion 7 to form a double-pipe structure, so that when water exists in the shower device 6, However, by reducing the amount of water remaining in the water supply pipe 73 rather than in the internal space of the device main body 60 and the arm portion 7, the chair 1 can be easily overturned due to the high center of gravity of the bathroom chair 1. Stabilization is prevented.

Furthermore, in the shower device 6 of the present embodiment, since the drain hole 80 is provided at the tip of the water supply pipe 73, especially when the arm portion 7 is turned downward to be in the stored state, the water Residual water accumulated in the water supply pipe 73 is drained through the water drain hole 80 by the inflow of external air from another nozzle 8 arranged on the root side (upper side) of the arm portion 7 rather than the drain hole 80 . The water is discharged to the outside of the supply pipe 73 and the arm portion 7, and the weight of the entire shower device 6 is reduced. Also, even when the shower hose or the like connected to the connecting portion 61 of the device main body 60 is removed, external air flows in from the connecting portion 61, so residual water accumulated in the water supply pipe 73 is drained through the drain hole 80. The water is discharged to the outside of the supply pipe 73 and the arm portion 7, and the weight of the entire shower device 6 is reduced.

As a result, the bathroom chair 1 to which the shower device 6 of this embodiment is attached facilitates the overturning of the chair 1 due to the high center of gravity of the bathroom chair 1 even when water exists in the shower device 6. , destabilization is prevented, and even when the front legs 20 and the rear legs 3 of the bathroom chair 1 are closed and folded, the bathroom chair 1 can be stably made independent.

In this embodiment, water is not directly passed through the device main body 60 and the arm portion 7, and the water supply pipe 73 is arranged in the device main body 60 and the arm portion 7 to form a double pipe structure. However, if it is possible to ensure the sealing performance of the moving parts of the main body 60 and the arms 70, 72, and 71, water can be directly passed through the main body 60 and the arms 7, and the arms A configuration may be adopted in which water is discharged from the nozzle 8 to the outside of the device main body 60 or the arm portion 7 by communicating with the nozzle 8 directly attached to the portion 7 . Further, in this case, by providing a drain hole 80 communicating with the inside at the tip of the second arm 71, the same effect as when the device body 60 and the inside of the arm 7 have a double pipe structure can be obtained. can be obtained.

In addition, when the device main body 60 and the inside of the arm part 7 have a double-pipe structure, even when not having a double-pipe structure, the drain hole 80 can also be used as the discharge hole (nozzle) 8, so that the shower device 6 , the drain hole 80 may function as the discharge hole (nozzle) 8. In this case, since only one nozzle is required for the drain hole 80 and the discharge hole 8, the shower device 6 can be configured with a very simple structure without requiring a special component such as an on-off valve.
